Sherman Maggard(s)

I am looking for information (proof) on Sherman Maggard that MAY have fathered Bluford Maggard (1901-1975), John H, Maggard (abt 1897) and Marion Maggard abt (1898).I have seen the census records of 1910-1930 (Letcher Co.)showing them with a Mother named Mary and living in their (Step-fathers) home (James H. Harper) for those years of 1910-1930.I have heard they are "possibly" the children of Sherman Maggard (abt 1871, s/o John and Mahala Rice-Maggard) and Mary Brown but I cannot find any marriage records of either one, nor can I find any birth/death certificates of any of the sons showing their Father.I was told there were other children also but I did not find them in the 1910-1930 census records.Any help?I am not the only one looking for this information and now that person asking me, has me on a rabbit trail.
